Giving preschoolers choice increases sharing behavior

Getting kids to share their toys is a never-ending battle, and compelling them to do so never seems to help. New research suggests that allowing children to make a choice to sacrifice their own toys in order to share with someone else makes them share more in the future. The new findings are published in Psychological Science, a journal of the Association for Psychological Science.

These experiments, conducted by psychological scientists Nadia Chernyak and Tamar Kushnir of Cornell University, suggest that sharing when given a difficult choice leads children to see themselves in a new, more beneficent light. Perceiving themselves as people who like to share makes them more likely to act in a prosocial manner in the future.

Previous research has shown that this idea - as described by the over-justification effect - explains why rewarding children for sharing can backfire. Children come to perceive themselves as people who don't like to share since they had to be rewarded for doing so. Because they don't view themselves as "sharers" they are less likely to share in the future.

Chernyak and Kushnir were interested in finding out whether freely chosen sacrifice might have the opposite effect on kids' willingness to share.

"Making difficult choices allows children to infer something important about themselves: In making choices that aren't necessarily easy, children might be able to infer their own prosociality."

Researchers debunk myth of right-brain and left-brain personality traits

Left and Right Brain

For years in popular culture, the terms left-brained and right-brained have come to refer to personality types, with an assumption that some people use the right side of their brain more, while some use the left side more.

Chances are, you've heard the label of being a "right-brained" or "left-brained" thinker. Logical, detail-oriented and analytical? That's left-brained behavior. Creative, thoughtful and subjective? Your brain's right side functions stronger - or so long-held assumptions suggest.

But newly released research findings from University of Utah neuroscientists assert that there is no evidence within brain imaging that indicates some people are right-brained or left-brained.

For years in popular culture, the terms left-brained and right-brained have come to refer to personality types, with an assumption that some people use the right side of their brain more, while some use the left side more.

Following a two-year study, University of Utah researchers have debunked that myth through identifying specific networks in the left and right brain that process lateralized functions.

Reza Aslan: Atheist Richard Dawkins is 'the worst kind of zealot'

When a video goes viral on the internet, you might expect it to feature a kitten dancing on a hippo, or Russell Brand telling an awards ceremony about breasts. Not a theologian putting a Fox News interviewer bang to rights on why he, a Muslim, had dared to write a book about Jesus. Yet a clip of Reza Aslan doing just that went viral this month, pushing his book to the top of bestseller lists.

"Just to be clear, this is not some attack on Christianity," he said of Zealot, a book describing Jesus of Nazareth as an illiterate, trouble-making social revolutionary (and a very inspirational one at that), to an anchor who could not get past his suspicious Muslimness. "My mother is a Christian, my wife is a Christian, my brother-in-law is an evangelical pastor." The anchor was undeterred, determined to reveal a secret Muslim agenda. "My job as a scholar of religions with a PhD in the subject is to write about religions," he insisted. The clip was watched and cheered by millions - it was extraordinary.

A magnetic trick to define consciousness

Consciousness
© Adenauer G. CasaliEchoes of awareness. Scientists can perturb the brain with a magnet and analyze its electrical response to measure consciousness.
Consciousness isn't easy to define, but we know it when we experience it. It's not so simple to decide when someone else is conscious, however, as doctors must sometimes do with patients who have suffered traumatic brain injury.

Now, researchers have come up with an approach that uses the brain's response to magnetic stimulation to judge a person's awareness, reducing it to a numerical score they call an index of consciousness.

"You're kind of banging on the brain and listening to the echo," says Anil Seth, a neuroscientist at the Sackler Centre for Consciousness Science at the University of Sussex in the United Kingdom who was not involved in the work.

Faced with an unresponsive patient, clinicians do their best to determine whether the person is conscious. Through sound, touch, and other stimuli, they try to provoke verbal responses, slight finger movements, or just a shifting gaze. Yet some conscious patients simply can't move or speak; an estimated 40% of those initially judged to be completely unaware are later found to have some level of consciousness.

Visualized heartbeat can trigger 'out-of-body experience'

A visual projection of human heartbeats can be used to generate an "out-of-body experience," according to new research to be published in Psychological Science, a journal of the Association for Psychological Science. The findings could inform new kinds of treatment for people with self-perception disorders, including anorexia.

The study, conducted by Jane Aspell of Anglia Ruskin University in the UK and Lukas Heydrich of the Swiss Federal Institute of Technology in Lausanne, is novel in that it shows that information about the internal state of the body - in this case, the heartbeat - can be used to change how people experience their own body and self.

Volunteers in the study were fitted with a head mounted display (HMD), which served as "virtual reality goggles." They were filmed in real time by a video camera connected to the HMD, which allowed them to view their own body standing two meters in front of them.

Why some remember dreams, others don't

Dreams
© DreamstimeWhat is the difference between people who always recall their dreams and those who rarely do?
People who tend to remember their dreams also respond more strongly than others to hearing their name when they're awake, new research suggests.

Everyone dreams during sleep, but not everyone recalls the mental escapade the next day, and scientists aren't sure why some people remember more than others.

To find out, researchers used electroencephalography to record the electrical activity in the brains of 36 people while the participants listened to background tunes, and occasionally heard their own first name. The brain measurements were taken during wakefulness and sleep. Half of the participants were called high recallers, because they reported remembering their dreams almost every day, whereas the other half, low recallers, said they only remembered their dreams once or twice a month.

When asleep, both groups showed similar changes in brain activity in response to hearing their names, which were played quietly enough not to wake them.

However, when awake, high recallers showed a more sustained decrease in a brain wave called the alpha wave when they heard their names, compared with the low recallers.

"It was quite surprising to see a difference between the groups during wakefulness," said study researcher Perrine Ruby, neuroscientist at Lyon Neuroscience Research Center in France.

The difference could reflect variations in the brains of high and low recallers that could have a role in how they dream, too, Ruby said.

Women still less likely to commit corporate fraud

Women are less likely to take part in corporate crime and fraud even though more women now work in corporations and serve at higher levels of those organizations, according to a team of sociologists.

The researchers examined a database of recent corporate frauds and found that women typically were not part of the conspiracy. When women did play a role, it was rarely a significant one.

"There has been this view for awhile that women are no more moral than men and that once there was more gender equality in the workforce, there would be more females involved in corporate crime," said Darrell Steffensmeier, professor of sociology and criminology, Penn State. "That view goes back a long time but, at some point, we should get the point that something else may be happening."

Steffensmeier said that about three out of four conspiracies to commit corporate fraud were all-male, and there was no report of an all-female conspiracy. In most cases when women do take part in corporate crime, they tend to play minor roles in the overall conspiracy, according to the researchers, who reported their findings in the current issue of the American Sociological Review.

Steffensmeier said the findings suggest that placing more women in executive leadership positions in corporations may raise ethical standards. Women are socialized to take fewer risks for business advantage and may feel they are under greater surveillance so they self-censor more, he added.

Electrical signatures of consciousness in the dying brain

A University of Michigan animal study shows high electrical activity in the brain after clinical death.

The near-death experience reported by cardiac arrest survivors worldwide may be grounded in science, according to research at the University of Michigan Health System.

Whether and how the dying brain is capable of generating conscious activity has been vigorously debated.

But in this week's PNAS Early Edition, a U-M study showed shortly after clinical death, in which the heart stops beating and blood stops flowing to the brain, rats display brain activity patterns characteristic of conscious perception.

"This study, performed in animals, is the first dealing with what happens to the neurophysiological state of the dying brain," says lead study author Jimo Borjigin, Ph.D., associate professor of molecular and integrative physiology and associate professor of neurology at the University of Michigan Medical School.

"It will form the foundation for future human studies investigating mental experiences occurring in the dying brain, including seeing light during cardiac arrest," she says.

Violent and abusive behavior against women, which can be both physically and emotionally harmful, gain societal acceptance when they are glamorized and normalized in popular culture such as books and movies. The main characters' relationship in the best-selling novel Fifty Shades of Grey, for example, helps perpetuate the problem of intimate partner violence against women, according to an article in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. To obtain a copy of the article, press contacts should email journalmarketing1@liebertpub.com.

In "'Double Crap!' Abuse and Harmed Identity in Fifty Shades of Grey," Amy Bonomi, PhD, MPH, Lauren Altenburger, BS, and Nicole Walton, MSW from The Ohio State University, Columbus, conducted a systematic analysis of the novel to elucidate patterns consistent with Centers for Disease Control and Prevention (CDC) definitions of interpersonal violence and associated reactions known to occur in abused women.

They conclude that the female partner, Anastasia, suffers harm as a result of her relationship with Christian. Specifically, the couple's interactions are emotionally abusive, characterized by stalking, intimidation, and isolation. Sexual violence is pervasive in the novel, including the use of alcohol to impair Anastasia's consent and the use of intimidation. Anastasia suffers stress, altered identity, and disempowerment/entrapment.

Tell me a story: Research examines how parents can use books to have a positive impact on their child's social struggles

New research explores the positive effects of reading as part of a parental intervention strategy for children struggling with social issues.


A new study out of the University of Cincinnati not only finds that parents feel responsible about taking action when their children struggle with social issues, but also that parents are influenced by their own childhood memories. Jennifer Davis Bowman, a recent graduate of the special education doctoral program at the University of Cincinnati, will present her research on Aug. 12, at the 108th annual meeting of the American Sociological Association in New York, N.Y.

Bowman's study examined parents' use of what's called bibliotherapy - using books as interventions for children who experience social struggles that may arise from disabilities such as autism or Down Syndrome.

Bibliotherapy involves books with characters that are facing challenges similar to their reading audience, or books that have stories that can generate ideas for problem-solving activities and discussions. Bowman says previous research found that bibliotherapy can improve communication, attitude and reduce aggression for children with social disabilities.

The adult participants in the study were four caregivers who had concerns about their child's social behavior. One of the participants was raising a grandchild. The other three were biological parents.
